'This invention relates to machines for refinishing shuttles-used in weaving machines, :whereby the life of :a shuttle is inat'erially increased. r

An object of the invention resides in providing a machine which is adapted to re- .fini'sh sh'u't'tlesused in weaving machines, in

faces thereof, so that the shuttle will not catch and breakpreviously woven threads.

Another" object of the inveiition resides in providing a shuttle refinishing machine for wearing-thesurfaces of shuttles, and for removing splinters and roughness from the surfaces of the shuttles, and provide a smooth exterior surface thereon, which consists in providing a carrier for mounting the shuttle, adjustable relative to a disc, faced with sand paper and rotatable during the refinishing operation, so that the carrier may be esitiened in spaced parallel relation, visit-respect to'tlie disc, in order that the shuttle may bereversed during the I refinishing o'peration o fi the several sides and properly squared during the operation.

The invention further comprehends the j provision of a machine having a pair of bar members mounting suitable block members in spacedrelation, carrying bearings for the shafts, mounting the rotatable disc having the sand papered surface, one of said bearings being of 7 an adjustable character, adapted. to take up endwise play in the shaft, while the other bearing includes a thrust bearing portion adapted to receive the thrust from the thrust collar on the shaft, in order that the face of the rotatable disc will be maintained in proper parallel rela- 7 tion with the shuttle carrier and adjustable on a suitable bracket mounted on the bar members between the block members, providing for accurately squaring the shuttle members, while refinishing thesame.

The invention also coniprehends other objects and improvements in the construction and arrangement of the parts of the dcvice, to produce a simple and inexpensive construction for carrying out the operation of refinishing shuttles, which are more particularly pointed out in the following description and claim, directed to a preferred form of the invention, it being understood, however, that various changes in the details of cons ruction and arrangement of the parts finishing machine. order to remove rough and splintered sur- 1924.

Aptur ofbar members are indicated at l,

which are mounted in spaced relation on -sui able end blocks 2 throughfthe medium of securing bolts and nuts indicated at 3,

cooperating with. suitable washers 4, the end blocks being adapted to be secured to suitable floor or other supports, in order to provide inounti rig for the machine. Block members 5 are-mounted in spaced relation, adjacent the opposite end portions ofthe bar members 2, at oneend, .as indicated ate, while the opposite ends o't'the block members project to one side of the barmembers, tor

rotatably mounting a, shaft 7, one of the block members carrying a pair of spaced bearings 8, rotatably receiving the shaft and mounting the same on the block member and between which a pulley 9 is mounted on the shaft, for receiving a belt'irom a suitable source OfPOWBl, one of the bearings 8 being adaptedto receive the thrust collar 10 on the shaft 7, in the manner clearly illustrated in Figure 1. The opposite end of the shaft is provided with a conical recess, for receivmg the pointed end of a thrust take up pin 11, which 18 screw threaded and mounted in a bracket 12; mounted on the other block member 5, a lock nut l3 being provided for locking the thrust take up pin,in such position, so that there will be no end play or looseness in the mounting of the shaft 7. A disc is mounted on said shaft adjacent one end thereof, which isindicated at 14, and which has one suriace or face provided with a sand paper covering, as indicated at if, the discbeing mounted on the shaft, in any suitable manner, well known in the art.

A bracket or rest 16 of angular form is provided with a securing foot 17. secured in a suitable manner to the bar members 1,

for supporting one portion of said rest, in a substantially hor zontal posit on, above the shaft 7, on which is mounted a carrier bar 18 for a shuttle. At the lower edge, the bar 18 is provided with laterally extending feet 19,'slotted as indicated at .20, to receive securing bolts 21, for holding the bar in a proper position of adjustment on the rest 16, and for guiding the same in its movement toward or away from the disc 14.

In refinishing a shuttle with this machine, the holder bar 18 is positioned parallel to the face of the disc 14 at a distance slightly less than the width of the shuttle to be refinished, and tightly secured in place, after which the shuttle is positioned on the rest 16, between the sand paper covered face 15 of the disc and the rest- 18, and moved across the rest between these elements, during the rotation of the disc, from a suitable source of power, at which time the sand paper will smoothly refinish one surface of the shuttle.

Following this, the shuttle is turned over to present another face to the sand paper surface of the disc, following which the above described operation is repeated, for refinishing this last mentioned surface of the shuttle, so that it will be seen that by repeating the operation all of the surfaces of the shuttle presented to the. thread during the weaving' operation will be smooth and free from splinters and the like, which frequently cause breakage of the thread. In this way, old shuttles can be refinished when required, so that the life thereof is substantially prolonged. The holding bar 18 is adjustable relative to the rest, so that the same may be set for varying sizes of shuttles, in an obvious manner.

From the foregoing description, it will be clear that a simple and efficient form of machine has been provided, which may be constructed at small cost, for refinishing shuttles of weaving machines, in order to prolong the useful life of the same.

What is claimed is:

A device of the class described, including bar members, a pair of blocks mounted in spaced relation on said bar members and secured thereto at one end, shaft bearings mounted on one of said bar members, a shaft rotatably mounted on said bearings raving a thrust collar adapted to eng ge one of said bearings, for receiving the eno thrust of said shaft, an adjustable bearing member on the other block member for the other end of said shaft, adapted to hold the thrust collar in engagement with the bearing, to prevent axial movement thereof in said bearing, a disc mounted for rotation on and with said shaft, having one face thereof provided vith abrasive material, a work rest mounted on said bar members, and a holding plate adjustably mounted on said rest adapted to be positioned in parallel spaced relation with respect to the abrasive covered face of said disc member, whereby shuttles may be passed between said disc and holding plate to hare the surfaces thereof squared and refinished.

In testimony whereof I aflix my signature.
